Supplementary 1

The finalized ranks of the Nobility of Westeros following Aenys's reforms are, from bottom to the top;

Baron, replacing the old titles of landed knight and Master titles. Also the title for clan leaders, no matter the origin. Female form, Baroness

Viscount, the title given to rulers of a City. Generally connected to a Count title, but not always. Female form, Viscountess

Count, the replacement for the lowest rank of the title of Lord. The ruler of a County District. Female form Countess

Duke, replacement title for the higher ranks of the old Lord title. The ruler of a Duchy District. Female form Duchess

Archduke, a Duke whose titles include more than one duchy. In the days of Aenys, there were 5 in Westeros. Manderly, Osgrey, Hightower, Peake, and Coldwater. Female form Archduchess.

Grand Duke, the replacement for the highest of Lordly Titles, the Lord Paramount. Technically, the old title of lord paramount was never abolished, and several houses kept styling themselves as lord paramount in addition to their titles of Grand Dukes. However, in legal documents and the popular consciousness, Aegon's old title of Lord Paramount was almost never used. Female form Grand Duchess.

Wardens, unchanged, but official reclassification as a title only active in war times. Gender-neutral title.

King, the monarch of the kingdom, owner of all land and the supreme head of the state of Westeros. From him, flows all justice and governing. Female form, Queen.

---

Landed prince, not above grand Dukes, but not below them either, all being direct vassals of the king. For example, the Prince of Firefield has his seat at the eastern edge of the Westerlands, yet is directly sworn to the crown. Note that the landed part of the title is merely an informative legal term to differentiate them from other princes, as it is never actually used to refer to them in a conversation. For example, the Prince of Dragonstone rather than the landed Prince of Dragonstone. Female form, Landed Princess.

Royal Governor, an appointed title which is not passed down to one's children, but nonetheless is in charge of a province. The most notable Royal Governor is, of course, the Royal Governor of the Stepstones. Though it was not intended for this to be the case, the title of Grand Duke of Sothoryos, eventually became a Royal Governor due to the fact that no Lordly Family lasted long enough in the position to form a continuous dynasty. Female form, Royal Governess.
